Cleaning Feathers

Cleaning feathers with the feet is one way to be certain that the hummingbird is cleaned each day. By using the feet, little bird will be able to use his claws to work the feathers around the eye to make certain those precious visionaries are protected. To actually watch them clean around they eyes, they move at such a rapid pace, one would think they are going to damage them, but they have a way to make certain they are careful not to damage the eyes.
Wikkiipedia states: "Towards the centre of the retina is the fovea which has a greater density of receptors and is the area of greatest forward visual acuity, i.e. sharpest, clearest detection of objects. In 54% of birds, including birds of prey, kingfishers, hummingbirds and swallows, there is second fovea for enhanced sideways viewing. The optic nerve is a bundle of nerve fibres which carry messages from the eye to the relevant parts of the brain and vice versa. Like mammals, birds have a small blind spot without photoreceptors at the optic disc, under which the optic nerve and blood vessels join the eye.[2]#irridescent feathers#male anna#hummingbird#bird#nature#tree#seed pod#cleaning feathers#eye
